The answer is x=-1.
•Multiply both sides by the Least Common Denominator:
2-4x=15+9x
•Subtract 2 from both sides:
-4x=15+9x−2
•Simplify 15+9x−2 to 9x+13:
-4x=9x+13
•Subtract 9x from both sides:
-13x=13
•Divide both sides by -13 and get your answer, x=-1.
Hope this helped!!

Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
y = -23(x + 9) + 4
y = 0
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in <em>y</em>: 0 = -23(x + 9) + 4
- [Subtraction Property of Equality] Subtract 4 on both sides: -4 = -23(x + 9)
- [Division Property of Equality] Divide -23 on both sides: 4/23 = x + 9
- [Subtraction Property of Equality] Subtract 9 on both sides: -203/23 = x
- Rewrite: x = -203/23
Y=mx+b
0=-1/2x-2
2=-1/2x
X= -4
We will set y=0 so we can know the value of x when line crosses the x axis
It is very important to look at the graph very minutely. It can be seen that at 30 minutes the slope is a little more than negative 50 and at <span>90 minutes it is a little less than negative 50. From this fact, it can be deduced that the estimated rate of </span><span>change of the temperature after an hour would be -50/60. I hope that the answer has come to your desired help.</span>
